Do you find it to dark? You will pump!

An exertion interface which the visitors have to use to keep the lights on.

Visitors use a bicycle pump to 'pump' light into the lamps around the room which will start leaking very slowly, lowering their brightness over time. Every once in a while a visitor has to pump again to keep the lights on the desired brightness.

Four times the same faces staring at you, constantly brushing his teeth. Creepy.

A DVD-loop showing me doing one of the things I could do all day: brushing my teeth.
